Brooke muses that it looked like they were having a moment. Ridge insists it was all about the necklace, and finds it cute she’s jealous.

Brooke sighs, “Here we go.” Ridge mentions divorcing Bill. Brooke admits she hasn’t even heard from him. Ridge asks her out for dinner, but learns Thorne is cooking her dinner…and living with her.

Brooke alludes to him having more in mind that shipping and receiving, and Ridge decides they should head to the office and find out.

At Forrester Creations, Thorne questions Eric about the identity of the woman Ridge cheated with. Eric gruffly says it’s not an issue anymore, and notes that Thorne has changed. Thorne admits he’s come back to be on equal footing with Ridge. He produces his designs, and says, “They’re mine. Ridge isn’t your only son who can design.” Thorne describes how he turned to designing in his grief, and received guidance from the best designers overseas. Eric asks if this is why he came back. Thorne glances at Brooke’s photo and replies, “One of the reasons.” He knows Ridge and Bill both let Brooke down, so when he heard she was getting divorced, he had to come back. Ridge arrives and admires the designs, admitting they’re good. Eric reveals, “They’re Thorne’s.” Ridge condescends that he draws pretty pictures, as Brooke joins them. Ridge calls Thorne out for going to Eric and Brooke before him. Thorne wants his opinion. Ridge complains there’s no theme and he’s an inexperienced designer.

In the design office, Brooke and Eric discuss Ridge and Thorne’s relationship with Quinn.Quinn-Eric-Ridge-Brooke-Thorne-boardroom-BB-CD Eric notes they’ve always been competitive, but Ridge always seems to get the upper hand.

At home in Malibu, Steffy cringes as she flashes to sex with Bill. Liam calls out to ask what she’d like on her sandwich, and brings her back to the present.

He asks, “Where did you go that night? What did you do?” Steffy flashes to sex with Bill again, as Liam wonders what made her come back home. She rambles that she should never have left; she should have stayed there. Liam questions if she spoke to someone who made her feel better – he’s trying to fill in the blanks.

Amid sex flashbacks, she becomes emotional, and blurts that she wants to erase that night. Liam vows never to let her down again. Steffy looks in the mirror and hears, “Liar! Guilty!” over and over.

In the bushes, Sheila watches the exchange. Thorne remarks to Brooke that she’s always been there for him, and she observes that he’s an amazing person. They are remembering their wedding in Venice when Ridge appears, and insists Brooke join him for an urgent meeting. Once alone, Thorne is joined by Sheila, who remarks on Ridge taking Brooke away as a lead-in to revealing that Ridge had an affair with Quinn.
